Corrosion-Resistant Quartz Glass | High Light Transmittance Window
| Custom-Shaped Quartz Glass
Fused quartz glass has become an essential material across
industries where extreme environmental conditions and high optical
precision are demanded. Our corrosion-resistant quartz glass
products are manufactured using high-purity silicon dioxide (SiO₂),
processed through electric fusion, and carefully shaped into both
standard and custom geometries. These glass components exhibit
excellent resistance to thermal shock, exceptional optical clarity,
and outstanding chemical inertness, making them ideal for both
harsh industrial environments and high-precision optical systems.
The high light transmittance window grade quartz glass offered here
combines durability with exceptional optical performance. Whether
you require planar substrates, sight glasses, lenses, tubes, or
complex custom components, our quartz glass solutions are tailored
to meet diverse specifications.

Q&A
Q1: What makes this quartz glass corrosion-resistant?
The extreme chemical purity and network structure of fused quartz
make it highly inert to almost all acids and bases, excluding
hydrofluoric acid. It outperforms borosilicate and soda-lime glass
in chemical resistance, making it ideal for harsh environments.
Q2: Can I request a custom shape or dimension?
Absolutely. We offer custom machining services, including CNC
shaping, waterjet cutting, ultrasonic drilling, and thermal
forming. Simply submit your drawing or 3D CAD model for a
quotation.
Q3: Is this quartz glass suitable for high-temperature
applications?
Yes, it can continuously withstand temperatures up to 1,100°C and
short-term exposure up to 1,250°C, with excellent resistance to
thermal shock.
Q4: Does this quartz glass support UV transmission?
Yes. Our high-purity fused quartz provides excellent transmission
in the UV range down to 200 nm, making it ideal for UV curing
systems, UV monitoring windows, and spectroscopy.
Q5: What are the standard lead times?
For in-stock standard shapes, delivery can be made within 3–7
working days. Custom parts typically require 2–4 weeks, depending
on complexity and volume.
